| 2d4+1d6+4+3d8 | Mix any number of dice groups and flat modifiers. + - * / ( ) all work. |
| d20 | Count defaults to 1. d% is a d100. |
| 4d6kh3 | Keep highest 3. Also kl keep lowest, dh drop highest, dl drop lowest. |
| d20adv / d20dis | Advantage / disadvantage (rolls twice, keeps the best / worst). |
| 3d6! | Exploding — a max face rolls again. !>=5 explodes on 5 or 6. |
| 4d6r1 | Reroll 1s once. ro = same, rr1 = reroll until it's gone. r<3 works too. |
| 2d6min2 | Treat any die below 2 as a 2. max5 caps each die. |
| 6d10>=7 | Dice pool: counts successes instead of summing. > >= < <= = supported. |
| 4dF | Fudge / Fate dice (−, 0, +). |
| 2d[Grit] | Any custom die by name — brackets optional: 2dGrit. |
| (2d6+3)*2 | Parentheses and multipliers for crit maths. |
